Personally, I think she is a little young for straightened hair. My daughter is also 3 and at this point, I would say that really isn't a necessary look on her, but that is just my own personal opinion. My older daughter who is almost 9 is allowed to get her hair straightened on special occasions only. That started probably when she was about 7. Maybe the other ladies will give you better feedback because
I may be a little old fashion.
